Presentations Due to Priapism in an Urban Hospital in Switzerland
Abstract
Objective: Priapism, a persisting erection not associated with sexual stimulation, can be ischaemic, with the risk of permanent erectile dysfunction, or nonischaemic. Drugs-e.g., injection therapies for erectile dysfunction, as well as neuroleptics, antidepressants and various other medicines-can also cause priapism. This study aimed to describe presentations due to priapism and provide insights into specific causes, clinical presentations, diagnostic strategies and emergency management.
Methods: A single-centre, retrospective, observational study of patients (≥ 16 years old) presenting to the University Hospital of Bern, Switzerland, between January 2010 and June 2023 due to priapism. The cases were retrieved from the electronic health records using full-text search.
Results: During the study period, 40 cases corresponding to 32 patients were included. The mean ± SD age was 48 ± 15 years, and pain was present in 21 cases (53%) on presentation. Median time of erection was 15 h (range: 1-80, n = 23). A penile blood gas analysis was performed in 32 cases (80%), and 29 of these (91%) were of the low-flow type. Most commonly suspected causes were idiopathic (n = 25, 63%) and drug-induced (n = 10, 25%). Suspected agents in the drug-induced cases were corpus cavernosum autoinjection therapy (n = 4), trazodone (n = 3), sildenafil (n = 2) and urapidil (n = 1). Puncture of the corpus cavernosum and injection of noradrenalin and adrenalin were the therapeutic measure in 35 cases…
